When location information is received from the information providing device 3, a route as shown in FIG. 3(b) is displayed.

By configuring the information providing system S in this way, the display device 1 can display arbitrary information (for example, advertisements) other than evacuation-related information in a situation where evacuation is not necessary, but when evacuation is necessary. In this case, it becomes possible for the user U to know the evacuation site. In addition, since the information acquisition image includes information indicating the installation location of the display device 1, even if the information terminal 2 is set not to transmit location information, the information terminal 2 can be used. This allows the user U to quickly move to an appropriate evacuation site.

Furthermore, the appropriate evacuation site may change depending on the location where the disaster occurred and the type of disaster that occurred. For example, if a fire or debris flow occurs, it is not appropriate to evacuate to an evacuation site near the area where the fire or debris flow occurred. Additionally, in the event of a tsunami, it is appropriate to evacuate to a higher elevation evacuation site. In the information providing system S, the display device 1 displays an information acquisition image in response to the occurrence of a disaster, and the information providing device 3 sends information indicating evacuation sites determined by local governments etc. to the information terminal 2. Since the information can be transmitted, even if the evacuation site changes depending on the location and type of disaster, the user U can quickly move to an appropriate evacuation site.
